ATTACHMENT FOR HARVESTER-REELS.

To all whom it may concern:

Be it known that I, ANDREAS M. Son- NIOHSEN, a citizen of the UnitedStates, residing at Milwaukee, county of Milwaukee, and State ofWisconsin, have invented new and useful Improvements in Attachments forHarvester-Reels, of which the following is a specification.

My invention relates to improvements in attachments for harvester reels.

The object of my invention is to provide simple and reliable means formanipulating rake teeth carried by the reel, whereby such teeth will beadjusted to raking position during the downward stroke and swung to atrailing position during the upward stroke, thus permitting the teeth towithdraw cleanly from the straw after picking up lodged straw andlifting it to the position where it will be properly cut by the sickle.

In the following description reference is had to the accompanyingdrawings, in which,

Figure 1 is an elevation of a reel embodying my invention. Fig. 2 is aview of the same as seen from the inner end, the reel supporting shaftbeing illustrated in cross section. Fig. 3 is an enlarged detailsectional view of the connection between the eccentric ring and one ofthe link rods.

Like parts are identified by the same reference characters throughoutthe several views.

A is a reel supporting shaft, B the radial arms of the reel and O thereel bars or bats. Rods D are mounted upon suitable supports in aposition to extend longitudinally along the rear surface of the bar O,preferably in close proximity to such bars and supported therefrom.These bars are mounted in bearings which permit an axial rotation andthey are provided with rake teeth E. They are also provided near theirinner ends with outwardly projecting arms F, connected by link rods Gwith the ring H encircling the shaft A, but eccentric thereto. The rodsG are formed in sections, adjustably connected with each other by acoupling member g, in which they are locked by means of set screws g.The inner sections of these link rods are loosely engaged in sockets Hin slotted projections h on the ring H, the slots h being arranged toextend radially so as to permit a lineal movement of the link rod. Theinner end of the inner section of the link rod is provided With an eyeIt which is loosely engaged Specification of Letters Patent.

Application filed October 25, 1907 Patented June 22, 1909.

in the socket H. A bolt S passes loosely through the slots h and throughthe eye R of the link rod, thus movably connecting the link rod with theprojection 72,. Buffer springs I are interposed between the projectionsit and a cross pin J on the link rod, these springs being arranged topush the link rods outwardly as far as the slots h will permit them tomove. In case the rake teeth meet with unusual resistance, however, theyare permitted to yield before the strain reaches the breaking point bypushing the link rods inwardly against the tension of the buffer springsI.

A bracket K is rigidly mounted upon a stationary collar L to which it isclamped by a yoke belt M and nuts m, and rollers O, mounted on thisbracket, are adapted to enter a channel P in the ring H and support thering in a position eccentric to the shaft A, the ring being otherwisesupported entirely from the rods D by means of the arms E and link rodconnections.

It will be observed that the bracket K, being supported in a stationaryposition from the frame sleeve L, a rotation of the reel Will becommunicated to the ring H, and as the latter revolves, each of the linkrods Will be pushed outwardly on the side occupied by the rollers 0,thus causing the rake teeth to swing outwardly to a radially projectingposition adapted to pick up fallen grain. The teeth of any given rakebar begin to retract as the corresponding reel arms B reach a verticalposition and the retracting movement continues on the upwardly movingside of the reel, so that the teeth will Withdraw from the tangledstraw. The bracket K can be adjusted on the collar L to any desiredposition by loosening the nuts m, and by this means the retractingmovement can be made to commence at any desired point in the circle ofrevolution.

Having thus described my invention What I claim as new and desire tosecure by Letters Patent is,

1. A reel provided with peripheral wings and axially oscillatory toothsupporting bars and rake teeth mounted thereon, in combination with arotary ring mounted upon a stationary support eccentric to the axis ofthe reel and arms rigidly connected with said bars and adjustable staysconnecting such arms with said ring.

2. A reel provided with fixed peripheral wings and oscillatory toothsupporting bars mounted thereon, in combination with a rotary ringmounted upon a stationary support eccentric to the axis of the reel,arms con nected with the oscillatory bars and link rods connecting eachof said arms with said ring.

3. A reel provided with peripheral axially oscillatory tooth supportingbars and rake teeth mounted thereon, in combination with a rotary ringmounted upon a stationary support eccentric to the axis of the reel,arms connected with said bars and link rods connecting each of said armswith said ring, said link rods being formed in adjustable sections andthe inner sections being resiliently connected with the ring.

4. The combination with a reel supporting shaft, a reel mounted thereon,tooth supporting members mounted for axial rotation near the peripheryof the reel, rake teeth mounted on said members and an actuating armconnected with each of such members, of a rotary ring encircling theshaft, a fixed bracket supporting said ring in a position eccentric tothe shaft, and link connections between the ring and the actuating armsof the tooth supporting members, said ring being provided with anannular channel in its inner surface and said bracket being providedWith rollers engaging in said channel on one side of the reel supportingshaft.

In testimony whereof I aflix my signature in the presence of twowitnesses.
